摘　　要：本文首先以一类由晶闸管控制的简单电力电子电路为例,引入器件开关模型阐明了存在的开关特性,并建立带开关函数的数学方程模型、分析了该特性对电路拓扑结构的改变。接着引入特征分析法量化这种变拓扑及可能存在的振荡,并给出了振荡的判别式和消除振荡的参数调整方法。最后通过算例仿真验证了变拓扑结构的模态影响以及特征振荡的调整参数消振法。This paper firstly shows that the switching characteristics of the power electronic devices with taking a type of simple circuits controlled by thyristors as an example.The variability of topology structure is analyzed.Then the eigen-analysis is introduced to quantify them and the possibly existed oscillation.The oscillation’s discriminants are deduced.The parameter adjustment method is proposed to eliminate the oscillation.Finally,a numeral simulation is carried out to verify the modal influence of variable topology and the proposed method.
